Audio Oscillator Circuits
 
  • CMOS SCHMITT TRIGGER IC MAKES VCO
    By changing the supply voltage fed to a classic 4584 Schmitt trigger type oscillator, the oscillator frequency can be changed over a range of 50:1.  A 74HCU04 inverter is used at the output of the 4584 to maintain a constant TTL logic level signal.
